In the plastic products industry, oiliness also refers to the problem of paint on the surface of the product after demolding or adhesion. Release agents that do not have paint and adhesion problems are called dry or neutral release agents. Of course, these are solvent-based release agents. Due to mold problems and operating time, the use range of water-based mold release agents is still limited, such as northern and winter, and the mold does not have a heating device, it is not practical. Generally speaking, the difference between oil-based mold release agent and water-based mold release agent is that the solvent is different, and the judging standard is generally based on flammability. The future trend is still water-based, non-solvated release agent.

The advantages of oil-based Mold Release Agent : good demolding, not easy to dirty the mold; disadvantages: less demolding times, easy foaming and delamination on the product surface, troublesome post-processing Advantages of water-based mold release agent: environmental protection (VOC emission is dominant), non-combustible (safe during transportation and use); Disadvantages: water recovery speed is relatively slow, molds are not easy to dry, due to surfactants, molds are easily dirty and demold The effect is not good enough. In addition, in the polyurethane foaming process, residual water will cause uneven cells. Oil-based mold release agents are mainly solvent-based mold release agents, which have good smoothness, but the release performance is not necessarily good.
